This page describes how to configure PPP dialup through a Bluetooth-compatible mobile phone. The emphasis is on using GPRS/EDGE services. These instruction were compiled and tested on Ubuntu 6.06 (Dapper Drake) on an IBM Think'Pad T40p with a Samsung T809 phone using T-Mobile's "Unlimited Internet VPN" plan.
Configure mobile phone data profiles
Getting the data access profile
T-Mobile
T-Mobile accounts generally require separate data profiles for WAP and general data access. (Some people have had success running a regular data connection over the WAP profile.) Getting access to general data access requires a data access plan. Currently, the "Unlimited Internet VPN" is the best deal, as it costs the same as the "Unlimited Internet" plan but gives you a real, public IP address. Incoming connections are blocked on any T-Mobile data plan. T-Mobile does not seem to offer metered data plans anymore. There are two ways to get the data service profile on your phone. Manual configuration is probably faster and better.
Automatic
T-Mobile can send the data services profile directly to your phone via SMS. Only the "wireless data" customer service people can send the data services profile to your phone. The regular service people can only send the WAP data profile, which will not work for general use. You will have to be transferred once or twice to reach the wireless data division. Once there, simply request that the data service profile for your plan be sent to your phone. (Of course, you'll need to be signed up for a data plan.) Once you receive the plan information, your phone will ask you where you want to store it. T-Mobile uses profile 1 for the WAP profile, so don't overwrite it. I recommend using profile 2, as it's usually the first empty profile. After storing the data services profile, your phone will probably set it as the default. This will probably cause your WAP (T-Zones/T-Mobile Internet) to fail for your on-phone browser. Set the WAP data profile (profile 1) to default fix this. See the configuration section below for your phone's brand. Setting the default profile is usually fairly obvious once you've reach the data services configuration screen.
Manual
Access the data profiles configuration for your phone's brand using the instructions under the configuration section below. The order and name for settings is for a Samsung T809. These settings are modified from the SMS T-Mobile sends Unlimited Internet VPN plan users. By adding the DNS and proxy information, you can use this profile for either T-Zones or general web browsing. Use the following settings for the Unlimited Internet VPN plan:
- Name:
T-Mobile VPN
- Home URL:
http://www.t-mobile.com
- Bearer:
GPRS only
- Proxy use:
Enable
- GPRS settings
- Proxy:
216.155.165.50
- Proxy Port:
8080
- DNS1:
216.155.175.105
- DNS2:
216.155.175.106
- APN:
internet3.voicestream.com
- Login ID: Empty
- Password: Empty
Other companies
Call your mobile service provider and request information about data plans. Many charge by the megabyte, but unlimited plans are increasingly available. Most of the instruction for T-Mobile will probably apply.
Configuration
Sony Ericsson GSM
This is from my memory of using a T610, but it should apply to any Sony Ericsson phone. Choose the lower-left icon from the main menu.
Samsung GSM
This is tested on a T809, but should apply to any Samsung GSM phone. Enter code
*#87927#
from the main screen. Select "Current profile" to choose the default profile. Select "Profile settings" to manage profiles.
LG GSM
This is tested on a CU 320 and works. If you have problems authenticating from the machine, discover it from the phone.
Installing Bluetooth and dialup packages
- If you have the
ubuntu-desktop
package installed, you can skip to the next section - Otherwise, run the following at a shell prompt; this should install the basic Bluetooth and PPP packages
sudo apt-get install bluez-utils bluez-pin ppp
Listing Bluetooth devices
- Make your phone Bluetooth discoverable.
- Run the following at a shell prompt:
hcitool scan
- Copy the MAC address (the text with the capital letters, numbers, and ':'s) somewhere convenient. You'll need it many times.
Pairing
You can skip this section if you've already paired your phone with your computer. However, consider the final optional step, as your phone might otherwise nag you every time you use if for dialup.
- Run the following, replacing your-phone-mac-address with the proper data
sudo hcitool cc your-phone-mac-address
- Run the following, replacing your-phone-mac-address with the proper data
sudo hcitool auth your-phone-mac-address
- If this command doesn't work, try the pairing instructions on other Bluetooth wiki pages; it seems 5.10 and older have issues with the PIN wrapper
- Enter a numeric code into the dialog box that pops up. If no dialog box pops up, run the following in another window
sudo passkey-agent --default /usr/bin/bluez-pin
- Accept the pairing from your phone handset.
- Enter the same number on your phone
- Run the
hcitool auth your-phone-mac-address
command again if it fails - You can remove your handset's Bluetooth discoverability now
- Some phones (notably Samsungs) require further authorization for certain Bluetooth activities, including dialup; consult your phone's user manual to avoid confirming your computer's dialup action on your phone every time
Note: I couldn't pair using the above instructions in Edgy. I had to install bluez-passkey-gnome, launch bt-applet (it's invisible when waiting), then initiate pairing from the phone. Note: I couldn't pair using the above instructions in Feisty. The pairing instead took place when I dialed the connection for the first time. I could not pair from the phone since my computer was hidden.
Configuring the rfcomm device
- Get the channel number for your phone's dialup service by running the following, replacing your-phone-mac-address with the proper data
sdptool browse your-phone-mac-address
- Look under "Service Name: Dial-up Networking"
- Under "Protocol Descriptor List:" and "RFCOMM", there should be a number after "Channel:"
- Remember that number; you'll need it for the rfcomm configuration
- Run
gksudo gedit /etc/bluetooth/rfcomm.conf
- Paste the following into the file, replacing your-phone-mac-address and your-phone-rfcomm-channel with appropriate values
rfcomm0 { bind yes; device your-phone-mac-address; channel your-phone-rfcomm-channel; comment "Bluetooth PPP Connection"; }
- Save and close the
rfcomm.conf
file - Run the following, which will create the rfcomm0 device
sudo /etc/init.d/bluez-utils restart
Note that on Edgy and Feisty the correct command is:
sudo /etc/init.d/bluetooth restart
Note: On the Nokia N95 (and possibly other Symbian S60 phones) the RFCOMM channel number is not consistent, but seems to change from time to time. If you have a phone that behaves like this, and you find youself unable to connect, you will need to re-run sdptool as described above to see if the channel number has changed. Rather than edit rfcomm.conf (and hence have RFCOMM bind to the channel at startup) you may find it more convenient to bind the RFCOMM channel on the command line:
rfcomm bind 0 your-phone-mac-address your-phone-rfcomm-channel
If you get the wrong channel (or if the wrong channel was bound at startup as a result of rfcomm.conf) then you need to release it before you can bind it again:
rfcomm release 0
Configuring PPP
- Run the following
gksudo gedit /etc/ppp/peers/BluetoothDialup
- Paste the following into the file (the file should start out blank)(I found that on my Motorola V360 that I had to comment out #lcp-echo-failure 0 useing T-Mobile.)
debug noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/BluetoothDialup" usepeerdns /dev/rfcomm0 115200 defaultroute crtscts lcp-echo-failure 0
- Save and close the
BluetoothDialup
file - Run the following
gksudo gedit /etc/chatscripts/BluetoothDialup
- Paste the following into the file (the file should start out blank), replacing your-apn-here with the APN from your data services profile and your-data-profile-number-here with the number you stored the profile into on the phone (probably 2).
TIMEOUT 35 ECHO ON ABORT '\nBUSY\r' ABORT '\nERROR\r' ABORT '\nNO ANSWER\r' ABORT '\nNO CARRIER\r' ABORT '\nNO DIALTONE\r' ABORT '\nRINGING\r\n\r\nRINGING\r' '' \rAT OK 'AT+CGDCONT=2,"IP","your-apn-here"' OK ATD*99***your-data-profile-number-here# CONNECT ""
Carrier specific configuration info
Phone specific configuration details
Samsung SGH-X820
This phone seems to have problems with various PPP options. Adding the following options to the relevant file in /etc/ppp/peers seemed to make it work.
nopcomp noaccomp nomagic receive-all noccp novj novjccomp
Authorizing dialout
- Run the following at a shell prompt, replacing your-username-here with your username:
sudo adduser your-username-here dialout
- This concludes the one-time setup
Connecting
Begin here on subsequent connections.
- If you have NetworkManager installed, right-click the applet and uncheck "Enable Wireless"; this will keep it from hopping onto wireless networks and botching your dialup DNS and default route settings
N.b. I do have NetworkManager installed and have found a work-around so that it doesn't mess with my connection over Bluetooth. I have not tried this in an environment where there are multiple WiFi connections _and_ yet I'm still trying to use the phone as a modem. The work-around is to edit the file /etc/network/interfaces and to add a line at the end of the file that reads:
iface hci0 inet static
- Run the following
pon BluetoothDialup
- Wait about 30-60 seconds
- You should now be able to ping
ubuntu.com
; expect latencies of around one second for most GPRS services - If pinging fails, see the troubleshooting section below
- See the disconnect section below when you're finished using the connection
PPP and TCP/IP troubleshooting
Try these troubleshooting sections in order.
Using the correct data plan
- Check that you're indeed using a real data profile, as WAP-only profiles generally disallow pinging, instant messaging, file sharing, and some web browsing
- Try setting the unrestricted data profile as your default data profile on your phone
- This will only work if the profile has proper DNS settings
- If you use the T-Mobile automatic profile setup listed above, it will not have proper on-phone DNS settings
- The manual method will work for T-Zones
- Use the built-in WAP browser to test the profile
- If it works, it's probably not your data plan (though it could be); continue troubleshooting below
- This will only work if the profile has proper DNS settings
PPP connection
- Monitor
/var/log/syslog
for dialup status information- The following indicates PPP success, where
xxx
s can be anything
- The following indicates PPP success, where
xxx localhost pppd[xxx]: Script /etc/ppp/ip-up finished (pid xxx), status = 0x0
Solution if problem
- Make sure there's not a PPP connection with
rfcomm0
already in session; runpoff BluetoothDialup
to disconnect one in session - Find where the error is in either the chatscripts or peers file
- Consult other help sources and update this page
IP address configuration
- Run
ifconfig
to check your PPP connection- The
ppp0
section should be as below, wherexxx
is anything
- The
ppp0 Link encap:Point-to-Point Protocol inet addr:xxx.xxx.xxx.xxx P-t-P:xxx.xxx.xxx.xxx Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:xxx errors:0 dropped:0 overruns:0 frame:0 TX packets:xxx errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:xxx RX bytes:xxx (xxx b) TX bytes:xxx (xxx b)
P-t-P:xxx.xxx.xxx.xxx
should match the address on the/var/log/syslog
linexxx localhost pppd[xxx]: remote IP address xxx.xxx.xxx.xxx
inet addr:xxx.xxx.xxx.xxx
should match the address on the/var/log/syslog
linexxx localhost pppd[xxx]: local IP address xxx.xxx.xxx.xxx
- If the addresses match, then your IP address configuration is probably fine
Solution if problem
- If a
/var/log/syslog
line seems absent, try reconnecting viapoff BluetoothDialup
andpon BluetoothDialup
- Make sure you're using the right data profile on your phone
Default route configuration
- Ping a valid public hostname on a connected computer, then (if it worked) try pinging the actual IP address from your PPP-connected computer
- If it didn't work, try pinging a different hostname; some block pings
- If this works, then your routing table is probably fine
- Check the routing table by running
route -n
- Your routing table should look like the following, where
xxx
is anything
- Your routing table should look like the following, where
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xxx.xxx.xxx.xxx * 255.255.255.255 UH 0 0 0 ppp0 default * 0.0.0.0 U 0 0 0 ppp0
- The
xxx.xxx.xxx.xxx
should match theP-t-P:xxx.xxx.xxx.xxx
in theifconfig
command'sppp0
block above - If the routing table checks out, routing is probably not the problem
Solutions if problem
Preferred method: Manually fix routing table
This needs instructions, as it should be the preferred method
Alternate method: Remove other interfaces
- Run the following
poff BluetoothDialup
- Remove any non-loopback and
ppp0
connections by running the following, replacing your-extra-interface with the appropriate names
sudo ifconfig your-extra-interface down
- Run the following
pon BluetoothDialup
DNS configuration
- Try pinging the DNS servers
- Try running
dig hostname-here
, wherehostname-here
is a valid hostname- If it resolves, DNS is probably not the problem
- Check
/etc/resolv.conf
to check your DNS configuration- Your routing table should look like the following, where
xxx
is anything
- Your routing table should look like the following, where
nameserver xxx.xxx.xxx.xxx nameserver xxx.xxx.xxx.xxx
- The lines above should match the
/var/log/syslog
lines like the following
xxx localhost pppd[xxx]: primary DNS address xxx.xxx.xxx.xxx xxx localhost pppd[xxx]: secondary DNS address xxx.xxx.xxx.xxx
Solution if problem
- If a
/var/log/syslog
line seems absent, try reconnecting viapoff BluetoothDialup
andpon BluetoothDialup
- Manually configure
/etc/resolv.conf
to point to your provider's DNS servers (or a public DNS server)- Try pinging the manually-configured DNS servers; if it fails only on the Bluetooth dialup machine, double-check the routing configuration
Disconnecting
- Run the following
poff BluetoothDialup
- Re-enable NetworkManager's connections, if you use NetworkManager
- Re-enable any other connections, as needed
